This is pertaining Ubuntu 18.04 LTS. I tried to save space by removing unneeded Linux kernel, but looks like it will still install other kernel image that is "Unsigned". Why is this?
Here is the log:
root@ubuntu18:~# apt-get remove linux-image-4.18.0-15-generic

After this operation, 168 MB disk space will be freed.
Do you want to continue? [Y/n]
The original Linux kernel version that ships with the distro appears to be version 4.18. The new version that was just installed was 5.0. So I wonder if there is a reason to "preserve" 4.18.
